Kolet does not provide a true unlimited data eSIM for Taiwan. All plans that are offered have a specified data cap. The plans that carry the label “UNLIMITED” deliver 5 GB of high‑speed data per day and, after that amount is used, the speed is reduced to 1024 kbps, so the data allowance is not unlimited.
Travelers who want a larger or longer‑validity option can choose from Kolet’s fixed data plans. For example, a 20 GB plan valid for 365 days costs $30.99 USD, while a 10 GB plan for the same period costs $19.99 USD. These plans offer large data allowances and remain at full speed throughout their validity, unlike the daily “UNLIMITED” plans that throttle speed after the daily limit is reached.
